Human rights and the 1980 U.S. presidential election

Due to dramatic developments in international affairs and the starkly diverging foreign policy visions of the two candidates, Jimmy Carter and Ronald Reagan, foreign policy occupied a usually prominent role in the 1980 U.S. presidential election. A central component of the foreign policy debate was the appropriate role for human rights concerns in American foreign relations. Nevertheless, neither

J/ψ production as a function of charged-particle multiplicity in p-Pb collisions at √sNN = 8.16 TeV

Inclusive J/ψ yields and average transverse momenta in p-Pb collisions at a center-of-mass energy per nucleon pair sNN = 8.16 TeV are measured as a function of the charged-particle pseudorapidity density with ALICE. The J/ψ mesons are reconstructed at forward (2.03 < ycms< 3.53) and backward (−4.46 < ycms< −2.96) center-of-mass rapidity in their dimuon decay channel while the charged-particle pseu

Spousal violence against women and its association with sociodemographic factors and husbands’ controlling behaviour : the findings of Myanmar Demographic and Health Survey (2015–2016)

Background: Spousal violence is the most common domestic violence against women and a growing public health problem globally. As a behaviour, marital control is commonly accepted as a precursor to spousal violence. Objective: This study examines the prevalence of different types of spousal violence among women in Myanmar and their association with sociodemographic factors and husbands’ controlling

Tramadol misuse in treatment-seeking adolescents and young adults with problematic substance use – Prediction of treatment retention

Non-medical prescription use of opioids (NMPUO) is a public health concern worldwide. Recently, tramadol misuse is increasing, but the systematic research of misuse of this specific opioid is limited. This study set out to assess the relationship between tramadol use and completion of treatment for substance use among adolescents and adults ≤ 25 years in an outpatient clinical setting. A retrospec

Periodic corner holes on the Si(111)-7×7 surface can trap silver atoms

Advancement in nanotechnology to a large extent depends on the ability to manipulate materials at the atomistic level, including positioning single atoms on the active sites of the surfaces of interest, promoting strong chemical bonding. Here, we report a long-time confinement of a single Ag atom inside a corner hole (CH) of the technologically relevant Si(111)-7×7 surface, which has comparable si

Rational Materials Design for In Operando Electropolymerization of Evolvable Organic Electrochemical Transistors

Organic electrochemical transistors formed by in operando electropolymerization of the semiconducting channel are increasingly becoming recognized as a simple and effective implementation of synapses in neuromorphic hardware. However, very few studies have reported the requirements that must be met to ensure that the polymer spreads along the substrate to form a functional conducting channel. The

Association between nutritional profiles of foods underlying Nutri-Score front-of-pack labels and mortality: EPIC cohort study in 10 European countries

Objective To determine if the Food Standards Agency nutrient profiling system (FSAm-NPS), which grades the nutritional quality of food products and is used to derive the Nutri-Score front-of-packet label to guide consumers towards healthier food choices, is associated with mortality. Design Population based cohort study. Setting European Prospective Investigation into Cancer and Nutrition (EPIC) c

Poly(alkanoyl isosorbide methacrylate)s: from amorphous to semi-crystalline and liquid crystalline biobased materials

We have prepared a series of twelve D-isosorbide-2-alkanoate-5-methacrylate monomers as single regioisomers with different pendant linear C2 to C20 alkanoyl chains by using biocatalytic and chemical acylations. By conventional radical polymerization, these monomers afforded high-molecular weight biobased poly(alkanoyl isosorbide methacrylate)s (PAIMAs). Samples with C2-C12 alkanoyl chains were amo

Rocking-Chair Proton Batteries with Conducting Redox Polymer Active Materials and Protic Ionic Liquid Electrolytes

Rechargeable batteries that use redox-active organic compounds are currently considered as an energy storage technology for the future. Functionalizing redox-active groups onto conducting polymers, to make conducting redox polymers (CRPs) can effectively solve the low conductivity and dissolution problems of redox-active compounds. Here we employ a solution-processible postdeposition polymerizatio

(Anti-)deuteron production in pp collisions at √s=13TeV

The study of (anti-)deuteron production in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. In this paper the production of (anti-)deuterons is studied as a function of the charged particle multiplicity in inelastic pp collisions at s=13 TeV using the ALICE experiment. Thanks to the large number of acc

Durable and highly proton conducting poly(arylene perfluorophenylphosphonic acid) membranes

Phosphonated aromatic polymers show several important advantages as proton exchange membranes (PEMs), including high thermal and chemical stability. However, the conductivity needs to be significantly enhanced for most electrochemical applications. Here, we have prepared a series poly(p-terphenyl perfluoroalkylene)s functionalized with highly acidic perfluorophenylphosphonic acid by first carrying

Simulating the recent impacts of multiple biotic disturbances on forest carbon cycling across the United States

Biotic disturbances (BDs, for example, insects, pathogens, and wildlife herbivory) substantially affect boreal and temperate forest ecosystems globally. However, accurate impact assessments comprising larger spatial scales are lacking to date although these are critically needed given the expected disturbance intensification under a warming climate. Hence, our quantitative knowledge on current and

Ubl4A is critical for mitochondrial fusion process under nutrient deprivation stress

Mitochondrial fusion and fission are dynamic processes regulated by the cellular microenvironment. Under nutrient starvation conditions, mitochondrial fusion is strengthened for energy conservation. We have previously shown that newborns of Ubl4A-deficient mice were more sensitive to starvation stress with a higher rate of mortality than their wild-type littermates. Ubl4A binds with the actin-rela

A 10-bit Split-Capacitor SAR ADC with DAC Imbalance Estimation and Calibration

This paper presents a 10-bit SAR ADC with a sampling rate of 200 MS/s. To reduce area and power consumption, the ADC adopts a split-capacitor DAC, where the gain error is estimated and subsequently removed by means of a PRBS signal injected into the DAC and detected at the ADC output. The ADC has been designed and fabricated in a 22nm FD-SOI CMOS process, and achieves an SNDR of 48.7 dB and an SFD

A Design Method to Minimize the Impact of Bit Conversion Errors in SAR ADCs

This paper analyzes the bit conversion errors in high speed SAR ADCs and proposes a design method to minimize their impact on the ADC performance. By removing the SR latch from the output stage of the differential comparator, while using only one comparator output to generate the differential signals for the internal capacitive DAC, sparkle-code errors are avoided, and conversion errors from a pre

Health-promoting and preventive interventions for community-dwelling older people published from inception to 2019 : a scoping review to guide decision making in a Swedish municipality context

Background: Despite the promising evidence of health-promoting and preventive interventions for maintaining health among older people, not all interventions can be implemented due to limited resources. Due to the variation of content in the interventions and the breadth of outcomes used to evaluate effects in such interventions, comparisons are difficult and the choice of which interventions to im

Low-lying electric dipole γ-continuum for the unstable 62,64Fe nuclei: Strength evolution with neutron number

The γ-ray emission from the nuclei 62,64Fe following Coulomb excitation at bombarding energy of 400-440 AMeV was measured with special focus on E1 transitions in the energy region 4-8 MeV. The unstable neutron-rich nuclei 62,64Fe were produced at the FAIR-GSI laboratories and selected with the FRS spectrometer. The γ decay was detected with AGATA. From the measured γ-ray spectra the summed E1 stre
